Detailed Description

This Nissens A/C hose assembly is engineered for the refrigerant discharge line, where pressure and flow consistency matter for proper system operation. The hose is specified for R134A systems and uses P-nut fittings on both ends, with a gasket or seal included to support a secure connection at installation. Part number 840071 cross-references OE numbers 1K0820721AA and 1K0820721BG for the same application.

Compatible With 2005-2014 Volkswagen Jetta, discharge line; 2010-2014 Volkswagen Golf, discharge line; and 2010 Volkswagen Golf SportWagen, discharge line. This makes it a practical replacement for drivers searching for a Volkswagen Golf A/C discharge hose, Volkswagen Jetta refrigerant discharge line, or Nissens 840071 hose assembly.

Common Problems This Part Can Address

• Refrigerant loss from a damaged or leaking discharge hose
• Reduced A/C performance caused by restricted refrigerant flow
• Failed hose connections at the discharge or suction ends
• Oil seepage at the hose sealing points
• Noise or vibration related to a deteriorated A/C line

Installation Notes and Tips

Verify refrigerant type before installation; this hose is specified for R134A systems. Inspect mating surfaces, replace worn seals as needed, and confirm the P-nut fittings seat correctly before evacuating and recharging the system. Because no manifold, mounting bracket, muffler, or service port is included, transfer or reuse the vehicle-specific components already on the car when applicable.

Quality Assurance

Nissens A/C hose assemblies are built to OE-level specifications for fit and function in the air conditioning system. Part number 840071 is intended for the listed Volkswagen Golf, Volkswagen Jetta, and Golf SportWagen discharge line applications.
